STEPS TO REPRODUCE 1. open Kate on Wayland session 2. switch to full screen mode by pressing ctrl+shift+f 3. OBSERVED RESULT Plasma panel is still visible EXPECTED RESULT Kate covers Plasma panel, like on X11 session. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.17.0 KDE Frameworks Version: 5.63.0 Qt Version: 5.13.1
I can reproduce it. I guess we don't support proper fullscreen mode at the moment.
It concerns either KWin or Plasmashell.
Seems to be solved in git master for plasma 5.18
